The installation position of the new anode has a great influence on the electrolytic cell, especially the height of the anode bottom palm. Therefore, it is necessary to calculate the thickness difference between the new electrode and the remaining electrode during the upgrading process. According to the new The difference in anode butt thickness calculates the distance required to move the anode bottom from the outside into the tank for a new anode bottom.
目前电解铝厂的换极技术主要有两种，一种是划线法，由操作工人接近残极划线，这种方法精确度低并且对人体危害比较大，另一种是使用测量参考平台，天车操作人员需要配合地面工作人员进行工作，实际使用也比较困难。At present, there are two main pole-changing technologies in electrolytic aluminum factories.
